# Arduino Makefile
# Arduino adaptation by mellis, eighthave, oli.keller
#
# This makefile allows you to build sketches from the command line
# without the Arduino environment (or Java).
#
# Note, this Makefile has been edited by the Debian package maintainer, so
# there's a reasonable chance it'll simply work without the need to edit it
# but just in case, here are the instructions:
#
# Detailed instructions for using the makefile:
#
#  1. Copy this file into the folder with your sketch. There should be a
#     file with the same name as the folder and with the extension .pde
#     (e.g. foo.pde in the foo/ folder).
#
#  2. Modify the line containg "INSTALL_DIR" to point to the directory that
#     contains the Arduino installation (for example, under Mac OS X, this
#     might be /Applications/arduino-0012).
#
#  3. Modify the line containing "PORT" to refer to the filename
#     representing the USB or serial connection to your Arduino board
#     (e.g. PORT = /dev/tty.USB0).  If the exact name of this file
#     changes, you can use * as a wildcard (e.g. PORT = /dev/tty.usb*).
#
#  4. Set the line containing "MCU" to match your board's processor. 
#     Older one's are atmega8 based, newer ones like Arduino Mini, Bluetooth
#     or Diecimila have the atmega168.  If you're using a LilyPad Arduino,
#     change F_CPU to 8000000.
#
#  5. At the command line, change to the directory containing your
#     program's file and the makefile.
#
#  6. Type "make" and press enter to compile/verify your program.
#
#  7. Type "make upload", reset your Arduino board, and press enter to
#     upload your program to the Arduino board.
